Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
98 words
A method of shaping a projected light pattern on a remote viewing surface comprising passing light from an incandescent source through a convoluted refracting element which has the property of intensifying and diminishing the projected light along irregular fixed paths on the remote surface by virtue of negative and positive areas of curvature on the refracting element; and interposIng a moving member consisting of various transparent color fields between the light source and the refracting element, the moving color fields producing a varying flow of colors along the fixed paths of light intensity on the remote viewing surface.
Claim 2
Independent Claim
98 words
A method of shaping a projected light pattern on a remote viewing surface comprising passing light from an incandescent source through a convoluted refracting element which has the property of intensifying and diminishing the projected light along irregular fixed paths on the remote surface by virtue of negative and positive areas of curvature on the refracting element; and interposIng a moving member consisting of various transparent color fields between the light source and the refracting element, the moving color fields producing a varying flow of colors along the fixed paths of light intensity on the remote viewing surface.
Claim 3
Dependent Claim
46 words
The method of claim 1 in which the moving color field is a moving endless belt of transparent material containing abstract patterns of transparent colors where the predominant direction of the color patterns is at an angle acute to the direction of motion of the belt.
Claim 4
Dependent Claim
23 words
The method of claim 1 in which the moving color field is a rotating disc of transparent material containing patterns of transparent colors.
Claim 5
Dependent Claim
21 words
The method of claim 1 in which the light is directed from a primary source and one or more deflecting surfaces.
Claim 6
Dependent Claim
13 words
The method of claim 4 where the reflecting surface is a convex mirror.
Claim 7
Independent Claim
144 words
An apparatus for projecting on a remote viewing surface a varying pattern of color images which pattern consists of flowing color changes along fixed flow paths of various light intensities, which comprises a housing open on one end, a light source positioned within the housing, a moving transparent multi-color member, including means for moving the multi-color member contained within the housing, the multi-color member being positioned between the light source and the open end, and positioned in the open end of the housing, a transparent convoluted refracting element for establishing the fixed flow paths, said element having a surface comprising a complex set of soft curves defining areas of shallow concavities joined by irregular regions of convexities providing non-uniform focal lengths which shape the projected light into the fixed paths of various intensities on the remote viewing surface along which the color changes flow.
Claim 8
Independent Claim
144 words
An apparatus for projecting on a remote viewing surface a varying pattern of color images which pattern consists of flowing color changes along fixed flow paths of various light intensities, which comprises a housing open on one end, a light source positioned within the housing, a moving transparent multi-color member, including means for moving the multi-color member contained within the housing, the multi-color member being positioned between the light source and the open end, and positioned in the open end of the housing, a transparent convoluted refracting element for establishing the fixed flow paths, said element having a surface comprising a complex set of soft curves defining areas of shallow concavities joined by irregular regions of convexities providing non-uniform focal lengths which shape the projected light into the fixed paths of various intensities on the remote viewing surface along which the color changes flow.
Claim 9
Dependent Claim
21 words
The apparatus of claim 6 in which the moving multi-color transparent element is a transparent rotating disc containing transparent color patterns.
Claim 10
Dependent Claim
20 words
The apparatus of claim 6 in which the moving multi-color transparent element is a moving endless belt of transparent colors.
Claim 11
Dependent Claim
18 words

Claim 12
Dependent Claim
14 words
The apparatus of claim 9 in which the reflecting surface is a convex mirror.
Claim 13
Dependent Claim
27 words
The apparatus of claim 8 in which the predominant direction of the color patterns is at an angle transverse to the direction of motion of the belt.
